Description
Technical field
It the utility model is related to brushless electric machine control technology field, more particularly to a kind of water pump brushless electric machine drive control system
System.
Background technology
Due to the rapid development of scientific and technological level, the technology of brushless electric machine has obtained very big development.Brushless electric machine, Yi Zhongyong
The low powered DC motor of electronic commutation, also known as commutatorless motor, commutatorless motor.The characteristics of it is maximum be exactly
Mechanical commutation is instead of with electronic commutation, mechanical commutation is overcome and brings the harm such as spark, noise, complicated, drop simultaneously
Low cost, makes the maintenance of motor become simple.Many brush motors in life instead of by brushless electric machine gradually, and it is extensive
Ground is applied to modern production equipment, instrument and meter, computer peripheral and smart appliances.
But current brushless electric machine also has the following disadvantages：Coefficient of friction between each structure is larger, loss increase,
Service life is caused accordingly to shorten；Motor working efficiency is low, and power output is small.
Utility model content
For above-mentioned weak point of the prior art, the purpose of this utility model is that operation can be reduced by providing one kind
Noise, energy-conservation, and improve the water pump Brushless Motors Drive System of motor working efficiency and delivery efficiency.
The utility model is achieved through the following technical solutions：
A kind of water pump Brushless Motors Drive System, including brushless electric machine, power supply, metal-oxide-semiconductor driving switch, hall sensing
Device, in addition to MCU chip, the MCU chip, metal-oxide-semiconductor driving switch, Hall sensor are connected with the power supply respectively, described
The output end of metal-oxide-semiconductor driving switch is connected with brushless electric machine, and the brushless electric machine is connected with the Hall sensor, the MCU
Chip receives the signal of Hall sensor, is handled through internal logic signal and outputs a signal to the metal-oxide-semiconductor driving switch.
The output signal of the MCU chip is pwm signal.
The power supply is 24 volts of dc sources.
The brushless electric machine includes motor magnetic sheet, rotor, motor stator, and the Hall sensor turns with the motor
Son is connected.
The beneficial effects of the utility model are：
The upper and lower bridge signals of PWM are exported using MCU chip, starts controlled motor and rotates, motor is detected by Hall sensor
Rotor output pulse width signal transduction rotates to MCU chip, feedback regulation motor, and running accuracy is high, it is steady to start, and reduces system
In rub between each structure, improve the operating efficiency and power output of motor operating, more save.
The quantity of the device of use greatly reduces, and volume-diminished, reduces cost.
Rotor is detected by Hall sensor, there are automatic protection functions.
Brief description of the drawings
Fig. 1 is water pump Brushless Motors Drive System schematic diagram of the present utility model
Embodiment
In order that technical problem, technical scheme and beneficial effect that the utility model solves are more clearly understood, below
In conjunction with the embodiments, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only
To explain the utility model, it is not used to limit the utility model.
As shown in figure 1, the present embodiment includes brushless electric machine, power supply, metal-oxide-semiconductor driving switch, Hall sensor, in addition to
MCU chip, the MCU chip, metal-oxide-semiconductor driving switch, Hall sensor are connected with power supply respectively, metal-oxide-semiconductor driving switch it is defeated
Go out end with brushless electric machine to be connected, brushless electric machine is connected with Hall sensor, and MCU chip receives the signal of Hall sensor, through interior
Portion's logical signal processing outputs a signal to metal-oxide-semiconductor driving switch, and metal-oxide-semiconductor driving switch can also be to under-voltage and overcurrent situation
Make a response, realize automatic protection functions.
In the present embodiment, the output signal of MCU chip is pwm signal.
In the present embodiment, power supply is 24 volts of dc sources.
In the present embodiment, brushless electric machine includes motor magnetic sheet, rotor, motor stator, Hall sensor and the electricity
Machine rotor is connected.
In this programme system, first, after switching on power, MCU chip, metal-oxide-semiconductor, Hall sensor are simultaneously at waiting signal
Reason, MCU chip inside carry out self-starting and export the upper and lower bridge signals of PWM, and in the presence of metal-oxide-semiconductor driving switch, electric current is sequentially
Machine winding is flowed through, so as to produce forward rotating excitation field, and is interacted with the magnet steel of rotor, makes rotor start to rotate, rotor
Hall sensor detects signal when having turned, and Hall sensor output pulse width signal is to MCU chip, by the logic of MCU chip
After processing, controlled motor normal work.
Preferred embodiment of the present utility model is the foregoing is only, not to limit the utility model, therefore, only
This is should be included in all any modification, equivalent and improvement that the utility model specification and drawings content is made etc.
Within the protection domain of utility model.
